Specification of Letters Patent.

Application filed December 28, 1911. Serial No. 668274.

T 0 all whom it may concern:

Be it known'that I, Znmn: E. NOAH, a citizen of the United States, and a resident of Greensboro, county of Guiltord, and State of North Carolina, have invented certain Improvements in Raw-Stock-Dyeing Machines, of which the following is a speci fication.

My inyention is an improvement in stock dyeing machines, and has for its object the provision of a machine which will take the stock and subject it. to a plurality of operations, compressing it after each operation.

In the drawings: Figure 1 is a longitudinal vertical section of the improvement; Fig. 2 is a plan view; F igi 3 is an enlarged sec' tion on the line 33 of Fig. l, and Fig. 4 is a similar sectionon the line 4% of Fig. 3.

In the present embodiment of the invention, a casing 1 is provided, having an open top, and divided by partitions 2, into a plurality of compartments 3', 4, '5, 6, and '7 respectively. It will be evidentthat the compartments might be replaced by separate casings .or tanks, it advisable. A pair of bracket plates are secured t: the casing at one end, each bracket comprising a side member 8 having at one end a depending lug 9 and at the other a leg 10. The depending lug-is secured to the casing by bolts 11, and theside members 8 a.re;connected by shafts 12, upon each of which mounted a roller 13. An endless apron 1.4 is supported on the rollers. 'The shafts 12- are in the same plane, and at-t-heinner end of the apron, a shaft 15 is jonrnaled between the side members above the plane of shafts 12, and a fluted roller 16 is secured to the shaft. The endless apron 14 is'coinposed of transversely arranged connected slats or bars, as shown, and roller 16 cooperates with the inner end of the apron.

A wringing or squeezing device is arranged at the rear side of each compartment, being supported on the side walls of the easing. Each of the said devices comprises a pair of superposed rollers 17 and 18 ar ranged transversely of the compartment, and journaled in oppositely arranged pairs of s andards 10. The members of each pair of standards are connected in spaced rehv tion by top plates 20, and the upper roller 18 is journaled in bear xg blocks 21, which are slidallle between the members oi the pairs of standards,and are pressed toward the lower roller by springs 22. A. counter shaft 23 is journaled in front of and between each pair of rollers 1'7 and 18, and a gear wheel 21 on the shaft meshes with a gear wheel 25 on the shaft of the roller 17.

A toothed wheel 26 is also secured to shaft 23, outside of the casing, and a sprocket wheel 27 issecured to the shaft, outside oi the toothed'wheel. A pair of pulleys, consisting of a fast pulley 28, and a loose pulley 29 is secured to one of the shat} 23"tor operating the rollers, and the Lid pulleys maybe engaged by a belt 2. power plant.

Eachcompartment isprovided with means for carrying the stock, as for instance cotton through the material in the said com artment, and as the arrangen'ientin all of t 1e compartments is the same, but one will be described. The said means coinprises a pair of e'ndless'belts or aprons 30 and 31. The members of each pair'have their adjacent runs in contact. The belt 30 is supported on a. roller 32 and the upper roller 18, and on rollers 33- 3435-36 and 37,

trom a suitable while belt 31 is also supported on rollers v the belts is carried backward and forward in the tank to thoroughly expose it to the action of the material in the compartment.

The rollers 32 and 38 are arranged near to the delivery side of the rollers 17 and 18 in all off-he compartments after the first, and in the first compartment the said rollers are in position to receive the cotton from the roller 16 and belt or apron 14. The rollers 32 and 38 are spaced apart horizontally so that the cotton may-pass easily between the belts. The rollers 37 and 39 are arranged almost directly below rollers and 3S, and the adjacent runs of the belts gradually ap preach, until they pass around roller 37' in contact.

The first compartment 3 of the carriage is for containing a suitable material in which to boil the cotton, as for instance water and ice a suitable detergent. Compartments 4 and 5 are for dye, compartment 6 is for con taining a suitable cleaning solution, and compartment 7 is for soap tor giving'the cotton a soap bath.

Above compartments 5 and 6 are arranged I endless apron-s 4O and-41 of wire gauze, they being supported withtheir inner runs adjacent and in inclined position, by means of rollers 42 and 43, arranged above and adjacent to rollers 32- and 3,8, and a pair of rollers 44 and 45 on the ceiling 46 of the room in which the vat or casing is support-- ed. The roller 43 is providedwith a gear wheel 47, which is connect-ed to gear wheel 25, by an idler gear 48, to drive thebelts 404l.

*1 operation, the cotton is fed to the space or throat 49 between belts and 31 atrollers 32 and 38, by the belt or conveyer l4, and is carried through the boiling material in compartment'3. After being thoroughly exposed to the action of the material in compartment 3, the cotton is compressed or squeezed by rollers 17 and 18, to free it from the material of compartment 3, and is delivered to compartment 4. The process is repeated in every compartment until the cotton isfinally delivered at the end of the casing,- remote from belt 14. As the cotton leaves the conveying device in the compartment or vat 4 it is fed from the rollers TIP--18 on to the upper face of the upper run of the gauze belt 41, and by this belt is cari'iedup to the ceiling 46 and over the roller 45 and is delivered "on ,to the upper run of the-gauze belt/40. The said belt passes the cotton downwardly and delivers it to the conveying deviceof vat 5. From vat 5 the rollers l7-18 deliver the cotton to the upper run of the gauze belt 41 above the compartment 6, and the apron 41 de livers the cotton to theapron 40 in the same manner as described for vat 4, and the said apron 4O delivers the cotton to the con reying means of vat 6. The cotton is thus exposed to the air after leaving vat 4, and before entering vat 5, and is similarly exposed between vats 5 and 6. The said exposure is for the purpose of oxidizing the cotton after being dyed in vat 4, and after being dyed in vat 5. This oxidizing is essential to the proper dyeing of the cotton.

The device is especially intended for indigo, raw stock, and the oxidizing process changes the color of the cotton from yellow as it comes out of the vat to a bluish shade before it enters the se ond vat. This change in "color can only be obtained by exposing the cotton to the air after the dyeing process. ,While, as before stated, the device is especially intended for indigo, the cotton may also be colored with other dyes than indigo, and in either case, the raw stock may I claim:
